TL;DR: In this article, a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts is described. But despite the diversity of the participants (230 scientists in total), the process revealed much about community priorities and the state of our science: a preference for continuity in research questions rather than radical departures or redirections from past and current work.

TL;DR: A filtration model that considers agglomeration in porous media and subsequent deposition explains the observed transport of polydisperse PSS-modified NZVI at high concentration.

TL;DR: The use of mass flux measurements (monitoring the concentration of contaminants in aqueous phase due to source zone NAPL-groundwater mass transfer) is introduced as a potential tool to assess the efficiency of technologies used in source zone remediation.

TL;DR: In this paper, a model is presented which describes in a simple way the transient process of infiltration, refreezing, and runoff in a future warming climate, applied to Greenland, for which predictions of runoff-induced sea level rise that do not consider the residual water content of the firn are as much as 5.0 cm too high over 150 years.

TL;DR: In this paper, an experimental study of the migration of denser-than-water nonaqueous-phase organic contaminants through heterogeneous porous media was carried out to gain a fundamental insight into the way aquifer heterogeneities influence the movement and subsequent distribution of immiscible contaminants after a spill.
